Our old BMtroubleu (BMW) d7 diesel had a magnito alternator. Which failed after 10 years use. We replaced it with a motor cycle copy which worked for a year or so before failing. I liked the concept no belts or pulleys but I guess the magnets didn't agree with the marine environment.

Magnetic fields are conservative fields and because of this, permanent magnets cannot be used to drive a motor. Unless you can somehow change the way the universe works. (Yes, I am a physicist and consequently a man of little 'faith')
